P-FINN: Polarity Test Sensor

The P-FINN is a cost effective method of identifying object presence and/or orientation, and/or color. The key to the design is simplicity which includes both an LED light source and a light sensor in an easy to mount assembly. It is available with blue, green and red light sources. The intensity of the reflected light is related to the color of the object. The output signal is proportional to the reflected light. The P-FINN is often used for component presence and component orientation.
